Fluid in the body's latent space
Virtually all latent spaces have surfaces that are roughly in contact with each other, with only a thin layer of fluid in between, and surfaces that slide on top of each other.
Some examples of "potential void" are the pleural space, the pericardial space, the peritoneal cavity, and the synovial space, including the synovial and synovial space.
Virtually all of these latent spaces have surfaces that are roughly in contact with each other, only a thin layer of fluid between them, and surfaces that slide on top of each other. To facilitate slipping, a viscous protein fluid will lubricate the surfaces.
The fluid is exchanged between the capillaries and the latent space
The surface membrane of the latent space usually does not produce a significant resistance to the movement of fluids, electrolytes or even proteins, all of which travel back and forth between the space and the interstitial fluid in the pulsed tissue. around relatively easily.
Hence, each latent space is in fact a large tissue space. Therefore, the fluid in the capillaries adjacent to the latent space diffuses not only into the interstitial fluid but also into the latent space.
Lymph vessels suck proteins from latent spaces
Protein collects in latent spaces by leaking out of capillaries, similar to the collection of proteins in interstitial spaces throughout the body.
Protein must be removed through the lymphatic system or other channels and returned to circulation. Each latent space is connected directly or indirectly to the lymphatic vessels. In some cases, such as the pleural and peritoneal cavity, large lymphatic vessels arise directly from the cavity itself.
Oedema in latent spaces is called an effusion
When oedema occurs in subcutaneous tissue adjacent to the latent space, oedema also often accumulates within the latent interval; This fluid is called an effusion. Therefore, lymphatic obstruction or any abnormality that can cause excessive filtration of the capillaries can cause effusion in the same way as interstitial oedema. The abdominal cavity is especially prone to accumulating effusion, and in this case, the effusion is called ascites. In severe cases, 20 litters or more of ascites can be accumulated.
Other latent compartments, such as the pleural space, the pericardial space, and the joint cavity, can become severely swollen with systemic oedema. In addition, local trauma or infection in any of the cavities often blocks the lymphatic drainage, causing separate swelling in the cavity.
Dynamics of fluid exchange in the pleural cavity. These dynamics also largely represent all other hidden spaces. Normal fluid pressure in most or all of the latent spaces in a state without plasma is negative just as this pressure is negative (under the atmosphere) in loose subcutaneous tissue. For example, the interstitial hydrostatic pressure is typically about -7 to -8 mm Hg in the pleural space, -3 to -5 mm Hg in the synovial space, and the pericardium -5 to -6 mm Hg i
